There are certain things that could be done to help the situation, I'm
not sure which would be best in your particular case but the current
sync_point setting could be turned into a general bitmask flags, where
sync point is just one and you can have codec specific allocations of
Also the check_buffer routine is called before the send_to_listener.
It's used to populate data from intro/fallback files or progress through
the queue. You could set a special check buffer handler that checks the
above refbuf_t flags. It's possible to create a per-client refbuf_t
within there that hooks back into the queue.
